The standard advice is three to six months of expenses. You've seen it everywhere. It's not wrong.
It's just written for a household that only has to look after itself.
Most of the people I sit with don't live in that household. They live in the one where the emergency fund is also the hospital fund for Papa, the tuition backup for a younger sibling, and the money that gets sent when Tita calls and says it's urgent. In that house, three months of your expenses runs out in about three weeks.
So let's do the honest version.
First, what an emergency fund is for
It has one job: to stop a bad month from becoming a bad year.
Without it, an emergency goes on a credit card, a salary loan, or a loan from someone who will mention it at every family gathering until you die. The emergency itself might cost ₱40,000. The way you paid for it can cost you far more, in interest and in relationships.
That's the whole case. An emergency fund isn't an investment. It earns very little, on purpose. It's insurance you pay for with patience.
Step 1: Find your real monthly number
Not your budget. Your actual spending. Look at the last three months of bank and e-wallet history and take the average.
Then add what you send. If you regularly support a parent or sibling, that's not optional spending. In a crisis, it's the last thing you'll stop. Put it in the number.
Step 2: Count the people, not just the months
Here's the adjustment the standard advice skips. List everyone who would realistically call you if something went wrong.
A rough way to think about it, and this is a starting point rather than a formula:
| Your situation | A sensible target | |---|---| | Single, no one depends on you | 3 months | | You support one other household regularly | 6 months | | You're the main support for parents or siblings | 6 months, plus a separate family buffer | | You're self-employed or on commission | Add 3 months to any of the above |
The "separate family buffer" matters. It's a smaller pot, set aside for their emergencies, so that a call from home doesn't empty the fund that's meant to keep your rent paid.
Step 3: Decide what counts
Write down, before anything happens, what the fund is allowed to pay for. Job loss. A hospital deposit. An urgent repair. A family medical emergency.
And what it isn't for. A sale. A trip. A cousin's business idea. A birthday you forgot was coming (that's a sinking fund's job).
People don't drain emergency funds on emergencies. They drain them on things that felt urgent for an afternoon.
Step 4: Build it in layers
Six months plus a family buffer can look impossible. So don't build it all at once.
Layer one: one month. This alone changes how a bad week feels. Layer two: three months. Layer three: the full target.
Celebrate each layer. Honestly. Most households never get to the first one.
Where to keep it
Somewhere boring, safe and reachable within a day or two. A separate savings account works. A digital bank's savings feature works. The rule is simple: not in the account you spend from, and not in anything that can lose value the week you need it.
What an emergency fund can't do
This part matters, because I see people try to make the fund do a job it was never built for.
An emergency fund can carry you through a few months. It can't carry you through a cancer diagnosis, a long hospitalisation, or the death of the person whose income keeps the house running. Those cost too much, for too long. That's what insurance is for: the big, rare things a savings account will never be large enough to cover.
The two work together. The fund handles the bad month. Insurance handles the catastrophe. If you only have one, you'll end up using it for the other's job.
This week
Work out your real monthly number, including what you send home. Multiply it by your target.
Then open a separate account, name it, and move something into it. Any amount. The first layer starts with the first peso.
